Liquid Magnetic Float Sensor, Flow range: 0 to 100 LPM, 25 mm

A Magnetic Float Sensor is a type of liquid level sensor used to detect the level of liquids in a tank or container. It operates using a reed switch and a magnet-embedded float. As the liquid level rises or falls, the float moves accordingly. When the float gets close to the reed switch, the magnetic field triggers the switch to open or close, indicating the presence or absence of liquid at a certain level.
